The situation in Iraq these days reminds me of how the Vietnam war ended. USA withdrew its forces. Thebrutal and corrupt regime in South Vietnam had no chance against the insurgents. It ended with a humiliating defeat in 1975.
In Iraq USA has choosen to support brutal, corrupt and divisive state leaders. The situation in Iraq is far worse than under Saddam. USAs invasion and later mismanagement of the country has caused a national disaster.
These days USA seems to being forced to cooperate with Iran in order to keep its puppet regime in Iraq floating. Still the future of this regime seems uncertain.
Let us hope the Iraqi people soon will get a government which prioritizes the welfare of the iraqi people and the national interests of Iraq.
I suspect you need a history lesson -
Perhaps you should review the Paris Peace Accords of 1973. Like we've done in Iraq, and are doing in Afghanistan, we managed to turn military victories into political defeats. I'll save you the collection of military history, but suffice it to say, the US military was very successful. The Paris Peace Accords was, effectively, our attempt to turn over military activities to the South Vietnamese government. One key element of PPA was a commitment, by the US, to provide $500 million in military armament support over 5 years. When our Democratically controlled Congress refused to fund that, the agreement fell apart.
So, we had a military solution that was undone by politicians.
Now, because our incompetent administration was unable to successfully negotiate a Status of Forces Agreement, we have people dying, uproar, and upheaval as the military solution in Iraq is undone due to the failure of the current administration.
Your comment - "The situation in Iraq is far worse than under Saddam." - borders on, in a word, nonsense. Maybe you want to tell that to the families of 3 million people gassed by Saddam, or the 5.5 million people who died as a result of his frequent purges and usurpation of charitable supplies. Or, perhaps, you want to ask the Iraqi people who have seen their average annual income increase over 300% since the overthrow of Saddam. Maybe you should ask the 97% about voting for the first time in their lives, braving machine gun nests and terrorist threats to try to establish democracy in their country. Ask them how much worse off they are.
As for the teeth gnashing and hand wringing about how bad it is - democracy is an ugly process. It ain't easy - there are fits and starts - there are skirmishes and squabbles - but, in the end, the people will have their say.
